Hide menubar and dock after fullscreen video in WebView

Question

I have a cocoa application which is a fullscreen webbrowser using WebView. Initially the menubar and dock are hidden, and cannot be accessed, which is how I want it, but after a fullscreen window such as a video is displayed, the menubar and dock reappear and stay there.

Any idea how to prevent them from reappearing?

Answer 1

I expect that the video player hid the already hidden menubar & dock when it went full screen. Then when it finished, it showed them again.

You'll probably have to hide them again yourself after the video is done..
